UNLV study unlocks clues to how planets form

EurekAlert! - Mar, 12/11/2018 - 23:00
UNLV researchers Shangjia Zhang and Zhaohuan Zhu led a team of international astronomers in a study that used the powerful ALMA telescope to discover that in other parts of the Milky Way Galaxy (seen here) there is potentially a large population of young planets -- similar in mass to Neptune or Jupiter -- at wide-orbit that are not detectable by other current planet searching techniques.

Live from the ocean research vessel Atlantis

Scientists and engineers on a deep-sea expedition aboard the research vessel Atlantis in the East Pacific Ocean will be broadcasting live to the American Geophysical Union fall meeting exhibit booth from 2:30 to 3:30 p.m. EST on Tuesday, Dec. 11, Wednesday, Dec. 12, and Thursday, Dec. 13.

Researchers report acute findings from Havana embassy phenomenon

EurekAlert! - Mar, 12/11/2018 - 23:00
Researchers from the University of Pittsburgh and University of Miami describe the acute symptoms and associated clinical findings following their assessment of 25 US diplomats living in Cuba.

Crashes increase when speed limits dip far below engineering recommendation

EurekAlert! - Mar, 12/11/2018 - 23:00
Speed limits set only five miles per hour below engineering recommendations produce a statistically significant decrease in total, fatal and injury crashes, and property-damage-only crashes, according to a group of Penn State researchers.

The epoch of planet formation, times twenty

EurekAlert! - Mar, 12/11/2018 - 23:00
A team of astronomers has conducted ALMA's first large-scale, high-resolution survey of protoplanetary disks, the belts of dust and gas around young stars.

Helping the anti-parasitic medicine go down

EurekAlert! - Mar, 12/11/2018 - 23:00
An international team has developed a novel pharmaceutical formulation to administer triclabendazole -- an anti-parasitic drug used to treat a type of flatworm infection -- in billions of tiny capsules.

Biologists shed new light on an old question

EurekAlert! - Mar, 12/11/2018 - 23:00
For nearly 100 years biologists have argued about how exactly natural selection can possibly work. If nature selects the individuals with the best genes then why aren't all organisms the same? What maintains the genetic variation that natural selection acts upon, the genetic variation that has ultimately led to the spectacular diversity of life on Earth today? Recent findings made at Uppsala University suggest that the answer could be sex.

Does work stress increase cancer risk?

EurekAlert! - Mar, 12/11/2018 - 23:00
In an International Journal of Cancer study of data on more than 280,000 people from North America and Europe, work stress was associated with a significantly increased risk of colorectal, esophagus, and lung cancers.

Researchers find clue to epidemics in 'bursty' social behavior

EurekAlert! - Mar, 12/11/2018 - 23:00
Researchers from NYU Tandon School of Engineering and Politecnico di Torino, Italy, have developed a mathematical model that could cure the potential to underestimate how quickly diseases spread. The team discovered that current predictive models may miss the influence of a critical aspect of the social behavior of individuals called 'burstiness.'

Study suggests improved compliance with the NIH sex as a biological variable policy

EurekAlert! - Mar, 12/11/2018 - 23:00
In 2016, the National Institutes of Health (NIH) implemented a policy which requires grant applicants to 'consider sex as a biological variable (SABV)' in vertebrate animal and human studies.

NASA examines reborn Tropical Cyclone Owen's temperatures

EurekAlert! - Mar, 12/11/2018 - 23:00
An infrared look by NASA's Aqua satellite found intense storms around the center of the recently revived Tropical Cyclone Owen.

Stanford researcher deciphers flows that help bacteria feed and organize biofilms

EurekAlert! - Mar, 12/11/2018 - 23:00
Figuring out how bacteria bring in nutrients could point to ways of killing them without poison. More generally, this research could also reveal how small organisms cooperate by generating networks of flow patterns.

An integrated approach to finding new treatments for breast cancer

EurekAlert! - Mar, 12/11/2018 - 23:00
An integrated, multipronged approach aiming at identifying therapeutic targets in cancer has uncovered gene DPYSL3 as a potential contributor to a specific subset of triple-negative breast cancer.

Resting easy: Oxygen promotes deep, restorative sleep, study shows

EurekAlert! - Mar, 12/11/2018 - 23:00
Exposure to high levels of oxygen encourages the brain to remain in deep, restorative sleep, according to a new study by University of Alberta neuroscientists.

Scientists identify new minerals for carbon capture

EurekAlert! - Mar, 12/11/2018 - 23:00
Research confirms new minerals are capturing and storing carbon in a new paper by University of Alberta geologists and their collaborators. The minerals, members of the hydrotalcite group, are the first outside of the carbonate family to naturally capture atmospheric CO2 in mine waste, important as society continues to forge ways to lower our carbon emissions and combat climate change.

No female mice? Scientists may still approve NIH grant

EurekAlert! - Mar, 12/11/2018 - 23:00
An increasing number of scientists are including female animals in their experimental designs and analyses for preclinical studies, as required by the National Institutes of Health (NIH) in January 2016, reports a new study. But NIH reviewers are not necessarily considering that inclusion when they score an application for funding, which was a goal of the requirement.

Clearest view ever of cell membrane yields unexpected structure, research possibilities

EurekAlert! - Mar, 12/11/2018 - 23:00
Working with a Nobel Prize-winning biophysicist, a team of researchers at Virginia Commonwealth University has gained the clearest view yet of a patch of cell membrane and its components, revealing unexpected structures and opening up new possibilities for pharmaceutical research.

Earth's cobalt deposits formed much later than previously believed

EurekAlert! - Mar, 12/11/2018 - 23:00
Cobalt deposits in the Democratic Republic of Congo, one of Earth's largest cobalt-mining regions, are 150 million years younger than previously thought, according to a new study by University of Alberta geologists. The study provides critical insight into exploration for cobalt, an important component in rechargeable batteries.

Record levels of mercury released by thawing permafrost in Canadian Arctic

EurekAlert! - Mar, 12/11/2018 - 23:00
Permafrost thaw slumps in the western Canadian Arctic are releasing record amounts of mercury into waterways, according to new research by University of Alberta ecologists.

Scientists to present new long-term ecological research findings

EurekAlert! - Mar, 12/11/2018 - 23:00
New results presented by National Science Foundation (NSF) Long-Term Ecological Research (LTER) scientists at the 2018 American Geophysical Union fall meeting reveal hidden realms in ice-covered lakes and deep soils. The conference will take place from Dec. 10 to Dec. 14 in Washington, D.C.
